e5eb9751f0 Initial `math/matrix' documentation, and some changes 
* At least stubbed out all (or almost all) `math/matrix' exports; many
  have complete documentation (e.g. types, predicates, accessors,
  constructors, for loops, conversion, much of "Comparing Matrices")

* Moved `matrix-zero?' and fixed to use (matrix-error-norm) as its norm

* Added `matrix-basis-cos-angle' (currently a stub; should return smallest
  singular value of a certain matrix multiplication)

55f98a15d4 racket/gui gtk: make `on-demand' for menus work better 
There appears to be no way to make `on-demand' work right for the
Unity window manager's global menu bar, since there's no notificiation
when the menu bar is clicked. We approximate the correct behavior
by calling `on-demand' when a containing frame loses the keyboard
focus, which might be because the menu bar was clicked; that may be
too late (because the menu has already been shown), but it should
work most of the time.

Closes PR 13347.

Relevant to PR 13395, but DrRacket will have to change to work
around the remaining limitations of `on-demand'.

* More accurate `flulp-error'

* Added `flonum->fields', `fields->flonum', `flonum->sig+exp',
  `sig+exp->flonum' (currently undocumented)

* Correctly rounded, robust `bigfloat->fl2' and `fl2'

* Correctly rounded, robust `fl+/error', `fl-/error', `fl*/error',
  `flsqr/error', `fl//error'

* Much faster but slightly less accurate fl2 ops (shamelessly stolen from
  crlibm, which is LGPL)

* Added `fl2ulp', `fl2ulp-error', `fl2?' (which detects overlap),
  `+max-fl2-subnormal.0' (which was tricky), `fl2abs'

* Added deterministic and randomized flonum op tests (against MPFR)

* Added deterministic and randomized flonum/error op tests (against MPFR)

* Added deterministic and randomized fl2 op tests (against MPFR)

* Exposed FPU tests in `math/utils' (currently undocumented)

f2d870859a logging: allow name in `log-message', report it in a log-receiver evt 
The synchronization result of a log receiver is now a vector of four
values, instead of three, where the last one reports the name.

Also, an optional argument to `make-logger' provides a notification
callback for each event sent to the logger.

These changes enable more control over loggers and events. Suppose
that you have processes A and B, and you want all log events of A
to be visible to B, but not vice-versa. Furthermore, you want the
log events to appear at B in the right order: if A logs an event
before B, then A's event should arrive at a log receiver's before
B's. Now that a log receiver gets the name associated with the
original event, and now that the name can be re-sent in a
`log-receiver', it's possible to give A and B separate loggers and
send all of the events from A's logger to B's logger. Furthermore,
you can use the notification callback so that when an event is logged
in B, you can make sure that all available events from from A's
logger have been transferred to B's logger.

d2d1ac2f2c Improve the logger GUI in DrRacket 
One drawback to the current situation (after this commit) is that all
log messages are sent into the user's logger, even messages that come
about as part of DrRacket's implementation. It isn't clear how to fix
this without enumerating all of the possible messages to share and
explicitly forwarding them (both of which are suboptimal things).

On the plus side, the GUI now uses the "debug@GC" notation in a text
field, and when the logger pane is not open, there is no extra work
going on. Plus other, minor GUI improvements.

b112a7ef0a adjust object-name on classes and interfaces to drop the prefix 
Before this commit, things like this:

  (define c% (class object% (super-new)))
  (object-name c%)

would produce

   'class:c%

but now classes and interfaces will be more like procedures and, in
the example above, just produce:

   'c%

The underlying goal is to make error messages generated from contracts
like

  (is-a?/c frame%)

have "(is-a?/c frame%)" in the message, instead of "(is-a?/c
class:frame%)"

a09c8f1857 Revert "racket/draw: fix another problem with the JPEG binding" 
This reverts commit c2468f1f9a.

The libjpeg documentation claims that it has no static state,
so atomic mode shouldn't be necessary. Also, the stress test is
still failing on some platforms, so there must be a different
problem than I thought.

1aebd171c5 Moar matrix review/refactoring 
* Consolidated Gauss and Gauss-Jordan elimination

* Fixed Gaussian elimination to return all indexes for pivotless columns,
  not just those < m

* Consolidated `matrix-row-echelon' and `matrix-reduced-row-echelon'

* Specialized row reduction for determinants; removed option to not do
  partial pivoting (it's never necessary otherwise)

* Added `matrix-invertible?'

* Removed `matrix-solve-many'; now `matrix-solve' solves for multiple
  columns

* Gave `matrix-inverse' and `matrix-solve' optional failure thunk arguments

* Made some functions that return multiple columns return arrays instead
  (i.e. `matrix-column-space')

* Added more tests

The version number is included as the query part of the constructed
URL, so it is easily ignored by a server. The intent is that the
PLT PNRs will eventually support version-specific results.
